How to zip Align APK file in android?

Question

I am uploading my first APK file to google play but I am getting following error.

You uploaded an APK that is not zip aligned. You will need to run a zip align tool on your APK and upload it again.

Can any one tell me how to zip align my apk file ?

Please tell me steps for that ?

Solution 1

Read the documentation from Google itself

The steps should be simple to follow.

Please follow this doc from google for complete publishing details

In short,complete steps in a nutshell(I am assuming you use eclipse/android sdk):

 1. Check android_manifest.xml and verify that android:debuggable  attribute is set to false in your manifest file            
 2. Check the android:versionCode and android:versionName attributes. 
    (if this is the first time you are uploading a apk,   
    ignore, else if it is a new version of existing apk, make sure these   
    values are larger than previous apk)
 3. Export unsigned application package from Eclipse
 4. Sign the application using release key certificate(not debug key certificate)
 5. Zip align the package
 6. Upload in google play

Solution 2

If you use Eclipse export wizard, it will automatically align it for you. However you can do it manually yourself

To align infile.apk and save it as outfile.apk:

zipalign [-f] [-v] <alignment> infile.apk outfile.apk

This website can provide more answers :) http://developer.android.com/tools/help/zipalign.html

Solution 3

try below link or code:-

To align infile.apk and save it as outfile.apk:

zipalign [-f] [-v] <alignment> infile.apk outfile.apk

To confirm the alignment of existing.apk:

zipalign -c -v <alignment> existing.apk

The is an integer that defines the byte-alignment boundaries. This must always be 4 (which provides 32-bit alignment) or else it effectively does nothing.

Flags:

-f : overwrite existing outfile.zip
-v : verbose output
-c : confirm the alignment of the given file

Solution 4

Check themanifest.xml file in your project it should say something like this:

android:debuggable="true"

set it to "false".

Solution 5

If you use eclipse the easiest way is to do it directly from it.

Go to "File" -> "Export" -> "Android Application Export"

The tool would ask you if you already have a keystore, if you do use it if not create a new one and save it on a safe place (you must remember the password so be sure to keep it somewhere you cannot lose it).

Then upload the file and there should be no errors.

Hey I am getting Error.. "You uploaded a debuggable APK. For security reasons you need to disable debugging before it can be published in Google Play. Learn more about debuggable APKs. You uploaded an APK that was signed in debug mode. You need to sign your APK in release mode. Learn more about signing."

Ok thanks Do i need to export unsigned APK file? acctully I had export signed apk file

[A Nice Guy]

yes you need to export unsigned apk file, and then sign it separately with a release certificate(if u export signed one, eclipse will sign with a debug certificate only, and google play doesn't like debug certificates)

<alignment> must always be 4

@LuckyyNickey: Please ask a different question rather than editing your solved question.

The <alignment> is an integer that defines the byte-alignment boundaries. This must always be 4 (which provides 32-bit alignment) or else it effectively does nothing.
